Tag managers

Tag managers load and control the third-party scripts on a website, from analytics and advertising pixels to chat widgets, through one container that marketers can change without a developer. The category is dominated by Google Tag Manager, with enterprise tag management from Tealium, Ensighten and Commanders Act TagCommander, server-side tagging through Addingwell SST, and Yottaa. Almost any business with a marketing function uses one, so the list spans small sites to enterprises. For lead generation the tag manager is a stack qualifier rather than a buyer signal: server-side or enterprise tools point to a data governance budget that suits analytics, consent management, customer data platform and privacy vendors.
